'To alZw-hom 'itmay concern: Be it known thatwe, -HEEBERTVWEBSTER and VSAMUEL Reimann, 'citizens of the United States, residing at Methuen, in the county of Essexy and 'State of Massachusetts, have invented new and useful Improvements in Looms, of which the following is a' specification. y v

The invention relates to ali-improvement in looms,f.and. is particularly directed to a stop mechanism arranged to be automat-` ically controlled by the shuttles, whereby when any two shuttlesare inline for. simultaneous operation the stop mechanism will be actuated and the loom stopped. i

.The mainvobject of the present inventionv is the provision of duplicate fingers arranged. for respective control by the shuttle box binder at each side of the lay, the alternate operation of'these fingers' 1n the .proper .feeding lofthe. shuttles being without effectl upon the stop mechanism, while their simultaneous operation by the presenceof alned shuttles will induce effective opera- .tion of the stop mechanism.

The invention will be described in the following s ecification, reference being had particular y to the accompanying drawings, in which A Figure 1 isa side elevation, illustrating the applicationand construction of our 1mprovement. Fig. 2 is a plan of the improved mechanism detached. tive of the rockerlever. Fi 4 is a per spective of one end of they' alance lever. Fig. 5 isa broken perspective of the slnpper rod arm. Fig. 6 is a broken perspective, showin the breast beam bridge and a' portion o the connection leading therefrom. Fig. V7 is a perspective showing in separated relationifthe connection between the linger rocker arms and the. rocker lever. Fig. 8 is a pers ective of the hook. late for connecting e spring for the alance lever. Fig. .9 is 'an enlargedsectional view illus .trating theinvention as applied to alain one shuttle loom. Fig. 10 1s a 1an o the ig. '11 isa perspective of the pintle plate.

Referring particularly to the. drawings, our improved mechanism comprises rock shafts 1y and 2 arranged respectively adjacent o posing endsl of the .loom lay 3, each oft e shafts being supported in bearing brackets 4 depending fromthe forward face of the lay,-so that the shafts are supj `a Abalance lever 12.

ig( 3 is a 'perspece ported in alinement longitudinally of and lslightly below the lay. At opposing ends of the respective shafts l and 2 there lis secured to each shaft a 'finger 5,' designed to be engaged and operated by the shuttle binder, whichfinger has a collar terminal 6 adaptedto-encircle the particular rocker 'shaft' and be lined in desired position thereon by a set screw 7. v

Secured to the under side of the lay, I.xdjacent the rear edge thereof, is a hanger arm 8, having a T-head 9 designed to en gage and be secured to the lay. The hanger arm is disposed about midway between the proximate ends of the rock shafts l and 2 yand is formed at its lower end with a bearing head 10, designed to receive a pin Il on which is movably mounted what we term .The lever is thus movably secured to the Vhanger arm Sand projects in both directions beyond the hanger arm, the forward projection being preferably of greater length than the rearward projection, the relatively upward movement of the forward end of the balance lever being limited by .a right angled stop plate 13 adjustably secured to the Y hanger arm through the medium of a pin and slot connection and having its relatively horizontal portion disposed imx the path of movement of the balance lever. The forward end of vthe balance lever is normally tensioned in an upward direction through the medium of a coil spring lil, secured to the balance lever at one end and at the opposite end to a hook plate l5, secured to the lay bar in an lappropriate manner. The relatively rear end of the balance lever is provided with a pivot intle 16and for the purposes of economy in construction and use we prefer to provide the pintle pin as an independent elel ment, casting the same integral with a plate ll', which is designed tobe screwed or other.-` wise removably secured to a similar plate 18 on the end of the balance lever, whereby renewal of the pintle 16 is permitted without the necessity of renewing the entire lever. 4 Y

Pivotally mounted upon the pin 16 is a rocker lever 19', preferably a narrow' strip of metal centrally formed with an opening 20. to engage ,the pin 16 and terminally formed wlth forwardly projecting pins 2l. The mountin of the rocker lever disposes the4 same at vright angles to thedirection-of the balance lever, and the respective endsl of Patented Feb. 22, 1910.

2 950,358 Y if the rocker lever are enga-ged by 4linlis 22 formed with bearing ends' 23 to-engage the pins'21, said -links being in turn and at their'v upper ends pivotally connected to levers 24' formed at one end with pins 25 to enfrage the.

bearings 26 atV the upper ends of the .links 22 and at the opposite 'end with bearings 2T to 'engage and be secured directlynpon the relatively inner ends of therock'shafts 1 and 2. The rocker lever is thus connected at each cud with the respective rock shafts 1 and 2, and intermediate said point of connection the rocker lever 1s fulcrurned or pivoiled upon a balance lever, which 1s without connection with the rocker shafts. Secured npon theV breast beam ofthe loom is a bridge piece 28, from -which projectsy rearwardly Aa' supporting arm' 29, the rear terminal of the arm 29 being arranged below .and immediately adjacent the connection of' the rocker lever 19 and balance vlever 12, as,

clearly shown in Fig.V 1. Pivotally oon- Anected to the rear end of the arm 29 is a trip lever 30, which projects toward and underlies theI forwardendv of the balance -lever 12, as clearly shownin Figs.`l and 2. Secured'to the trip lever'30 is a 'trip arm 31, preferablyA fixed to -the said trip lever 30 through the medium of a pin and goislot connection 32, whereby the trip arm 3l vious that as' long as the shuttle boxes and may be adj usted longitudinally with relationto the trip lever 30. The arm 31 carries a vertically offset or '.trip projection 33, designed to directly underlie 4the :treeA end of the balance lever 12, and said balance leverv 12 at itsr free end is branched to provide arms`34, which'rotatlvely support aroller 35 designed, when the parts are in normal position, to bear directly upon .the tri projection 33. AThe'trip arm 31 exten s forwardly through the bridge piece 28, prefer'- ably extending through a guide housing 36 formed integral with 'the bridge piece, as clearly shown in Fig. 6. bridge piece the forward end of the trip arm is designed -to rest upon a horn- 37 projecting laterally from a hook arm 38 secured shuttles are operating in' relation, the mechanism described will not be a'ected, as the arrangement of the particular box and tlie movement of the 'shuttle will cause a succesl sive operation of the fingers 5, which novement simply rocks the rocker lever` 19 Aon its ivotal su port land in nowse affects the' alance o -the mechanism. If, however, from any cause two shuttles are 1n line in -`arms extend I beneath the lay Beyond the thc raceway, both of the lingers 5 will be4 si@ anism `to theres ective ends of the rocker lever- 19, it isobvlous that said lever' will be bodily raisedl The raising ofthe lever will force the -forward end ofl the balance` lever 12 downward and thereby through the prolayand through the horn 37' rock .the shipper rod to stop the iooin.

lVth the mechanism.describediin position it will beim ossible fortwo shuttles to be simultaneous ydriven from' opposite ends of the lay, as the .position of saidshuttlcs for -drivingfwill lmmcdia'telyfand simulta-V neouslye'ect bo'th fingers 5 .without the ef-V feet described; The parts are adjustable so that they may bev connected with particularregard to the loonrwith which they are to bc'used, and mthis connection -it is to bc mult'aneously operated? As these fingers are respectively connectedthrough lever mech-4 ;jcction 33 onfthe trip arm 31 will de res'rs rsaid arm on the forwardmovcmento the understodxthat there is no limitation as to vthe size or material of the Arespective parts.

'.lieferring articularlytoFigs. 9 to 11the invention 1s s iownasaplplied to a lain one shuttle loom'inrwliich t e pintle ate 41 is secured directly. to the vrear side o mount arocker, lever 43corresponding t0 the rocker-lever 19of,the construction previously'dcscribed. Secured tothe ends of the 'lay 3, -on the intle 42' of which plate i's pivotally the rocker lever. are; depending links 44 terminally connected' tor lever arms 45, .which and are fixed to the relatively inner terminals of rods JR mounted in bearing strips 47 secured' to the relatively Aforward edge of the' lay. The re- A mote .or relatively outer ends of the rods project-beyond the' adjacent bearing'stri s and carry fin ers 48 terminating above'tie lay in the hoo ends '49. .In the use of this form ofthe invention the fingers 48 act alterna'tely under the influence of the moving shuttle, so'that when one iingr vis outwardly dis )osed' with respect to the inder, as when a slhuttle is" within the box,.-the' opposing finger at the 'opposite endo the lay isinwardly dispose so as to act s an automatic lock on thebinder adjacent thatA particular finger. Therefore, when a shuttleis in 'one box the opp site box is vlocked and a shuttle cannot be inserted in the latter box.
